Answer: 385
Step-by-step explanation:
Mean the three groups of 10 kids=35
Total weight of 3 groups (10x35)=350
Mean weight of 3 groups and one boy ( 35 + 350)=385
You can find this answer multiple ways.
One way is to represent it as an equation and solve for x, The total number of vehicles.
0.4x = 98
x = 245 vehicles
Or write a proportion using the fraction for 40%.
2/5 = 98/x
5 x 49 = 245
There are 245 vehicles in the garage.
Answer:
Yes; she will have $4008 for other expenses.
Step-by-step explanation:
First you find out how much she saved by multiplying 350 by 36 as she saved for 3 years which is 36 months.

After that you need to work out the amount she needs in total for her tuition by multiplying 4 by 3723 which is the amount needed per year.

If her parents add to her account half the amount she saved that means that they give her an additional 6300 as that's half of 12600.
This means she has 18900 and if you take away 14892 you will be left with 4008 for expenses.
Answer:
the mean is 9.
Step-by-step explanation:
<h2>mean=<u>4+4+5+6+8+9+27</u></h2>
7
<h2>= <u>63</u></h2><h2> 7</h2><h2> 9 is the answer.</h2>
Change the x and y
Then solve for y
X= 8y+1
Subtract 1 from both sides
X-1=8y
Divide by 8
X-1 /8 = y
